It is a companion code that was stored! It could mean a lot of things, and i believe you have to go to the stealership to let them pull it! I had one that said coolant temp too hot too long!

Some auto parts stores will scan your truck for free. All that code means is there is another code in either the PCM or ECM.

yeah but most autoparts stores don't have a nice enough scanner to even pick up a companion code!

If you were around me I could scan it for you.
